Frequency=f
T=period of motion
f=1/T therefore f=1/2=0.500Hz or 0.5Hz
Hope this helps. Any questions please just ask. Thank you.
Ans: Radiocarbon dating uses carbon isotopes.
Radiocarbon dating relies on the carbon isotopes carbon-14 and carbon-12. Scientists are looking for the ratio of those two isotopes in a sample. Most carbon on Earth exists as the very stable isotope carbon-12, with a very small amount as carbon-13.
Answer:
See the explanation below.
Explanation:
53) Yes, this process is called latent heat transfer, it happens when heat is transferred to a body or a substance, an increase in its energy is observed without presenting an increase in temperature. An example of this can be seen in the evaporation of water.
54) It absorbs energy since heat transfer always occurs from a space of higher temperature to another with lower temperature so as the wax freezes the heat is transferred from the environment to the wax.
55) The water vapor and wet air will be absorbed by the canvas, the heat contained in this water vapor will be absorbed by the canvas in this way decreases the temperature of the water inside the canteen.
56) The process is vaporization. The refrigerant of the air conditioning equipment enters the coil, in the form of liquid, this liquid is at low temperature, so that the room air at a higher temperature, exchanges heat with the refrigerant liquid, the refrigerant liquid changes the phase of liquid to vapor, for when it is completely vaporized this can be sucked by the compressor equipment.
